Population ecology of the edible dormouse. Habitat use and reproduction under difficult environmental conditions

Beech trees produce nutritious seeds at unpredictable intervals. Further, she presents data on body mass and reproduction at a climatically challenging site. The book addresses ecologists, wildlife managers, and others interested in small mammal biology. Consumers of such pulsed resources are often generalists that exhibit population growth following a mast fruiting event. She combined large scale terrain characteristics with small scale habitat parameters measured around nest sites. The edible dormouse (Glis glis). Which factors determine habitat use in the dormouse? How much is juvenile development influenced by food availability? Dormice are able to anticipate a future mast situation, allowing them to synchronize reproduction with high food availability – or skip it entirely in the absence of seeds. The author Birgit Rotter used GIS technology to incorporate topographic features in the development of a species-habitat model. Considering their strong adaptations, this study aims to investigate the influence of woodland composition on the species‘ ecology. However, one mammal shows maybe uniquely distinct adaptations to seed production:

Species-oriented Model Approaches to Daphnia. Linking the Individual Level to the Population Level Книга по Требованию Instead of following a ? problem-oriented? paradigm applicable to a single, well defined problem or scientific hypothesis, the underlying concept of the emerging model system was considered to be ? species-oriented? . Thus, various relevant processes are included into the framework in order to simulate the dynamics of daphnids displayed on different levels of biological organization Although its central role in applied and basic research in aquatic ecology is obvious, there are still fundamental problems in modelling the observed dynamics of Daphnia (for details see chapter 2). Therefore, a basic motivation of this work was to use scientific results obtained in independently conducted research for developing a model that brings these results into context.2784 руб
